ACCESSORY FOR MOTOR-VEHICLES.

Application filed August 10, 1917. Serial No.

To all whom it may concern.

Be it known that I, JOSEPH BIJUR, a citizen of the United States, and aresident of the borough of Manhattan, in the city, county, and State ofNew York, have invented an Improvement in Accessories forMotor-Vehicles, of which the following is a specification.

This invention relates to electrical apparatus and with regard tocertain more specific features, to the mounting of a dynamoelectric-machine and related powertransmitting parts.

One of the objects thereof is to provide apparatus of the above type ofenhanced simplicity and effectiveness. Another object is to provide asimple, secure and inexpensive mounting for an electric, starting motorwith relation to an internal combustion engine. Another object is toprovide a mounting of the above type in which the apparatus is readilyassembled ordismounted and is nevertheless rigidly held assembled incondition for eflicient action.

Other objects willsbe in part obvious and in part pointed outhereinafter.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth, and the scope ofthe application of which will be indicated in the following claims.

In the accompanying drawings in which is shown one embodiment of thisinvention, Figure 1 is a side view partly in section showing themounting of the apparatus on an automobile engine, part of theconstruction being broken away.

Flg. 2 is a View similar to-Fig. 1 with the device in position to bewithdrawn from the engine.

Fig. 3 is a fragmentary end view of the device showing a preferredmounting of the motor relative to the flywheel. Similar referencecharacters refer to similar parts throughout the difierent views of thedrawings.

Referring now to the figures of the drawing, there is shown afragmentary portion of an engine having a circular opening 2, the edges3-4 of said opening only being machined to form a mounting in which theapparatus may be rotated by hand. The

Specification of Letters Patent.

machined portions shown for only a short distance thus dispenslng withthe necessity for machining the inner port on 5 of this opening, whichinner portion 15 preferably made of larger diameter.

The starting motor 6 of usual construction, which need not be describedin detail, has an end head 7 preferably having a flange overlapp ng theyoke 8. Preferably integral with the end head 7 and eccentric withrespect thereto there is a circular pilot 13, the edges 17 and 18 ofwhich are accurately machined to fit within the machined surfaces 3 and4 above described. The intermediate portion of said pilot is preferablymade of smaller diameter for convenience of manufacture and assembly.Coaxial with the armature shaft and therefore eccentric with respect tothe pilot is the bearing 23 the washer 24 and lockring 25 maintainingthe bearing, the armature shaft and the hub in proper relative position.A screw 14 preferably extends from a tapped opening 15 in casing 1 intoan opening 16 in the hub 13, securely maintaining the apparatus inposition. An oil well 22 extends from the outside of the casing tobearing 23.

On the extension 9 of the armature shaft there is mounted a transmittingmechanism preferably of the screw shift type which need not here bedescribed in detail as it is the subject matter of the co-pendingapplication of Joseph Bijur, Serial No. 145,839 filed February 1, 1917.It may be briefly noted that the screw shift consists of a pinion 10adapted to cooperate with the flywheel gear 11, the inertia of a nut 19threaded upon shaft 9 as at 20 and located within the barrel 12transmitting longitu- (linal movementto the pinion 10 through the spring21 to cause it to cooperate with gear 11 tostart the engine. started itimparts such 10 as to transmit to the nut an angular velocity greaterthan that ofthe shaft so that it will override the screw-threadedportion and draw the pinion out of mesh with the flywheel. By referringto F ig. 1, .it will be seen that the barrel 12 is larger in diameterthan the pinion 10 and extends to a point within the contour of theflywheel gear 11 so that it would be very diflicult if not impossible,without special arrangements, to

speed to the pinion withdraw the motor and its attached screw shift fromthe casing as the pinion 10 or the barrel 12 would strike the flywheel11.

Further detailed description of the screwshift is not necessary as thiselement in itself does not constitute a part of the present invention.It is to be understood that other forms of power-transmitting devicesmay be used to advantage but there are particularly beneficial featuresin the use of the specific form of screw shift shown.

The construction of the apparatus having thus been described and theshift being assumed to be already mounted on the extended motor shaft,the manner of attaching the unit to the engine is substantially asfollows:

With the portion of the hub nearest the flange 7 brought into alinementwith that portion of the opening 2 nearest the flywheel, the end of theshift is inserted into this opening and the pilot will follow, themachined surfaces 17 and 18 fitting snugly in the machined surfaces 3and 4:. The device is now in the position shown in Fig. 2. The motor isnow grasped and the casing rotated through an angle of approximately 180degrees. This, as is readily understood, will cause the axis of themotor and its extended shaft to move through an arc of a circle with thecenter of the pilot as its axis from the position shown in Fig. 2 tothat shown in Fig. 1 until the screw shift is in proper positionrelative to the flywheel gear as shown in Fig. 1, when opening 16 in thehub will register with the tapped opening 15 in the casing and screw llmay be inserted and the device secured in position.

If, for any reason, it be desired to remove the motor this may be doneby simply reversing the operations above described. The screw s isremoved, the motor casing is turned through 180 degrees, thus movin theshift and its barrel out of alinement with the edge of flywheel 11 whenthe motor and its attached shift may be withdrawn from the engine casingas a unit by a simple longitudinal movement.

If the pilot instead of being made eccentric as above described weremade concentric with the shaft or if any concentric form of mounting beprovided. more particularly with an inboard shift of the type disclosed.it is obvious that it would be very inconvenient. if not impossible, toremove the motor from the casing without detaching the shift or somepart thereof from the motor. In addition to the greater amount of timeconsumed in doing this it is to be noted that. there would be greatdifficulty" in getting at the shift, particularly in the case of aninclosed casing.

There are some designs of engine on the 's a circular opening enginecasing havmarlret in which there like opening 2. in ti e anaem a ing afixed relation to the flywheel. In such cases if the axes of the pilot,screw shift and the flywheel were arranged in a single plane the bearingof the armature, of course, being within the pilot it frequently happensthat the rotation of the motor in the manner above described would notremove the screw shift sufliciently from the flywheel to enable thebarrel member 12 to clear the edge of the flywheel.

In such cases the arrangement shown in Fig. 3 is preferably employed. Inthis figure similar parts bear the same reference numerals as in Figs. 1and 2, except that they are primed. Instead of arranging the three axesin a single plane, it is noted that the axis E of the pinion is offsetfrom the line A-ll connecting the axis of the pilot with that of theflywheel. The diameter of the pinion having a definite value to procurethe power ratio desired. this axis must obviously be located upon arcC-D concentric with the flywheel. In the preferred form the axis of theshift is located at the point of intersection of this arc with theperpendicular dropped from the pilot axis A. With the arrangement justdescribed if it is desired to remove the motor from the casing it isonly necessary, after taking out the fastening screw to rotate thedevice in a clockwise direction until the pinion axis E is on thecontinuation of line A-B. By this process it is seen that the axis ofthe screw shift has been displaced from the flywheel by the distance F-Gwhich is sufficient to enable the barrel 12 to clear the flywheel 11.

If the axis of the screw shift were located at the point F on the lineA-B. it is obvious that a rotation of the device would effect only adisplacement of the shift with respect to the pinion by a distance equalto twice tr-F. In the device shown this would not be sufficient toenable the barrel to clear the flywheel edge.

It is, of course, obvious that the axis of the shift need not be locatedat the point E, but may be positioned at any point on the arc (-D. Iflocated below point Fl shown in Fig. 3. an even greater displacement ofthe pinion from the flywheel would be secured than. in the case shown.

It will thus be seen that thereis herein described apparatus in whichthe several features of this invention are embodied. and which apparatusin its action attains the various objects of the invention and is wellsuited to meet the requirements ofpractical use.

As many changes could be made in the above construction. and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting sense.
